CONNECTING POWER VENTER TO APPLIANCE

The venting system should be installed and supported in accordance with the National Flue Gas Code, ANSI Z223.1, 
CGA Standards B149.1-M91, B149.2-M91, or in accordance with any local codes. A vent pipe connector shall be 
supported for the design and weight of the material employed, to maintain clearances, prevent physical damage and 
separation of joints. 
If mounting venting system near combustible materials, refer to Diagram B for allowable installation clearances. Always 
check local code requirements for code restrictions. 
Route the vent pipe from the appliance to the power venter using the minimum number of elbows necessary. The 
horizontal section of the vent pipe should have a slight upward slope from the appliance to the power venter. For 
clearances to combustible materials, multiple appliance venting, and other installation requirements, refer to the National 
Fuel Gas Code ANSI Z223.1, CGA Standards B149.1-M91, B149.2-M91, and/or any applicable local codes or appliance 
manufacturer's installation instructions.

NOTE:

Vent pipe joints should be secured with at least three sheet metal screws.

Use a PEK series extension kit or follow installation method below for a double pipe system. When the outer pipe of the 
SWG is extended over the inner pipe, use the double pipe guidelines for determining clearances. 

INSTALLATION USING TYPE B VENT PIPE

1.  Using a hand crimper or a like device, crimp the inner pipe of the SWG power 

venter approximately 1" long. (See Figure 4) 

2.  Attach the vent pipe over the crimped end of the SWG power venter inner pipe. 
3.  Secure the vent pipe to the SWG power venter inner pipe with at least (3) three 

#8 sheet metal screws. Pre-drilling the holes through both pipes will allow easi-
er fastening.
